I'm not sure that anyone would have used it anyway, but where the heck was this a couple weeks ago when everyone hoarded all the toilet paper?!
A new website called HowMuchToiletPaper.com will tell you how long your current supply will last, based on what you've got and how often you're hitting the bathroom.
And after playing around with it, you really don't need much. So may I suggest donating some our that surplus to someone who still can't get any?!
